SYSTEM CAPABLE OF ADJUSTING CLOCK PHASE OF AD CONVERTER

摘要

PROBLEM TO BE SOLVED: To provide an analog/digital converter with improved performance when clock noise interference is present.

SOLUTION: The system comprises a clock phase shifter 85 that is controlled so that a converter can operate at the optimum sampling time interval with respect to interference noise. The phase shifter comprises a device to generate multiple sampling clock phases and a multiplexer 82 that is connected to multiple phase inputs to select the optimum clock phase, and operates the analog/digital converter by selecting one of the optimum clock phase.
